Yes, there is no way to configure the X server. The X people refuse to store configuration in the X server so you need a daemon to configure every device as it is attached. For some reason you can configure keyboard layout with udev but nothing else can be configured in X. You need a daemon to configure monitors, a daemon to configure input devices, and a daemon to configure wacom tablets because the wacom people can't agree with X people on a protocol that would allow configuring Wacom tablets *and* other input devices. You can only configure a device once connected and the configuration is lost once disconnected unless a deamon is watching for device hotplugs and reconfigures any new devices. You can also write a configuration file which has completely different syntax and option names from xrandr/xinput/xsetwacom and requires you to restart the X session. Very consistent and practical. nVidia control panel used this method last time I tried it.
